SBM heads

They look like Aeroflow castings, china cast but the casting quality looks better than the edelbrock heads. Would be interesting to see how the grade of alloy compares to what edelbrock use.
Doesn't list a price on their website though - the Aeroflow heads I bought needed the valve job fixed (badly chattered) and a couple of the guides were a little bit tight.
If this mob are checking them over and giving them a decent valve job they're probably a good starting point.
